How to Fix / Troubleshooting

Safety: Disconnect power before working near the blower or PCB.

Steps:

Check for obstructions: Remove the front cover and filters. Inspect the blower wheel for foreign objects (plastic, insulation, insects) preventing rotation. Remove any debris.
Spin test: Gently rotate the blower by hand. It should spin freely without grinding. If stiff or noisy, the motor bearings may be failing.
Inspect wiring: Locate the indoor fan motor connector on the PCB. Reseat the connector and check for corrosion or burnt pins.
Test operation: Restore power and run the fan-only mode. If the fan does not start or starts then stops with E7, the motor or its hall sensor is likely faulty.
Replace motor: Remove the blower assembly according to the service manual and install a new Electrolux indoor DC fan motor. Ensure correct wiring and secure mounting.

If a new motor does not resolve E7, the indoor PCB fan driver circuit may need replacement.

Indoor unit displays E7 and may not respond to remote commands
